Unfortunately, despite of google claiming so in the header, it's not
BSD-licensed but GPLed.  However, the author's name and email address
are given in the code (and we've heard of him before in AVR-land), so
you could ask him whether he'd like to contribute it to avr-libc under
a BSD-style license.

Yes, we'd definitely welcome it in the form of a patch, ready for
integration, including doxygen-style comments for the documentation.

Because it once started out as a header file containing three
different CRC-16 calculations.  The iButton CRC-8 had been added
later on.
